AD 284-305: "During the reigns immediately prior to Diocletian, the weight of the gold aureus fluctuated wildly, from as heavy as 6.90 grams to as light as 4 grams, and seemed to vary almost arbitrarily from mint to mint. This irregularity continued into the first years of the new regime (see previous lot), but between AD 286 and 290, Diocletian stabilized the aureus at 60 to the pound, or about 5.46 grams of gold, throughout the Roman Empire."
